    Is it possible to fix Nelson Muffler

    Hi

    I have several nelson mufflers broken from the ear where screws hold.

    I have tried to sold them with aluminum and making the hole again without any success, the soldering is not strong enough and mufflers keep coming out specialy from the screw at the back.

    Is there any way to try fixing these mufflers or is it a lost case.

    Kind regards.
    Victor.

    For most folks Bill is correct. 

    But, if you have access to someone with a TIG welder they can build up the broken area with weld and then machine it  back to specification it will work fine.  To just take it down to a weld shop would be quite expensive but, if you took all of them at the same time and you did your own post welding machine work it shouldn't be to bad.

    Funny, I have been contemplating that very thing. I wondered if you can tig weld on that cast aluminum. It's not so much about cost now that you can't buy replacement ultratrust mufflers.

    Thanks

    With a good sand blast prior to welding Barry is right. I've done it a few times.

    Most likely fading away till the My Forums is fixed. Too bad.

    If you read Mike Langlois thread/post on the N-40 going back into production line 7 states: (7. In the future we will be offering Ultra thrust mufflers. ) So the Ultra thrust mufflers will be in production again.

    That's good news but it says future. You can't buy them now nor get them repaired so this welding ideal might just work. Also, they may not be offering SS mufflers since they only plan to make LS engines.

    Thanks Vic for reminding folks that with welding, especially TIG, that the metal prep is paramont to having a decent weld that doesn't fall apart. Especially oil. There are special washes and preps but brake clean and good old soap and water with a good rinse due well and there are other special washes that can be used but, cost is a factor.

    If you sand blast it make sure to clean everything good with soap and water when you are done. Don't want to suck any nasty back into the engine.

    I have welded several TT mufflers and MVVS header pipe connectors in the past.
